Subject: feat(java): Implement Java catalog management and download features

- Added commands to fetch and refresh the Java catalog, cancel downloads, and manage pending downloads.
- Enhanced the Java download modal in the UI to support version selection, download progress, and pending downloads.
- Introduced new types for Java catalog, download progress, and pending downloads.
- Updated settings store to handle Java catalog state, download progress, and pending downloads.
- Improved user experience with loading states, error handling, and status notifications for Java installations.
